Automatically Highlighting A Bar Chart

I'm currently writing an automatic report to display information about a store and how it compares to its peers. My company works on a National>Region>Area>Store basis so my report lets a user select a store and the excel file brings back all the data for the relevant national, region and area data for comparison. That works fine.

I now want to develop a set of pages which display data for that store compared to other stores in the same area. For example: [URL]

My report brings back all the stores, ranks them by their performance against target and then puts them in a sorted table using vlookups. I then want to put them into the bar chart shown above, with the store selected highlighted with a different colour. In the example above, the Hunslet store is selected so its bar is highlighted.

Is there any way to make the store highlight automatic? I manually set the colours in the example but I don't want the user to have to do that each time. It would be possible to do using a macro, but I try and avoid them where I can since VBA knowledge is extremely limited in my office.

I have named ranges containing the names and lookup codes for the selected store, area and region .
